LOCK-NUT FOR VEHICLE-NUTS OR THE LIKE.

SPECIFICATION forming part of Letters Patent No. 789,059, dated May 2,1905.

Application filed May 12, 1904. Serial No. 207,581-

To (all whom, it 7771a, concern:

Be it known that I, GEORGE W. PETER, a citizen of the United States, anda resident of St. Louis, Missouri, have invented new and usefulImprovements in Lock-Nuts for Vehiole-Nuts or the Like, of which thefollowing is a specification.

This invention relates to lock-nuts for vehicle-axles and the like; andit consists of the novel construction, combination, and arrangement ofparts hereinafter shown, described, and claimed; and it has for itsobject to provide means in combination with an axle-nut and the likewhereby the same will be positively locked against accidental backwardrotation, thereby removing all danger of loss and the incidentalinconveniences.

Figure 1 is a sectional view of the nut locked home. Fig. 2 is aperspective view of a part of the axle, showing the construction used inthis invention. Fig. 3 shows the locking devices in the arrangements topermit removal of the nut. Fig. 4 shows the position of the lockingdevices when the nut is locked on the axles.

1 indicates a portion of an axle, and 2 the threads, outward from whichthere is an unthreaded portion 3.

The nut 4 is of the usual hollow type and carries in its extreme depth alocking device 5, which in the form shown is a spring band or plateretained by suitable means and having one end projecting helicallyinward from the inner side of the nut, as shown in Fig. 4:- On theunthreaded outer end 2 of the axle there is formed a series of notches,shoulders, or projections 6, which have flat surfaces on the side towardthe inner pitch of the threads 2, while the projecting end of the springor device 5 is arranged oppositely, so that the nut may be screwed ontothe threads, the end of the spring being dragged over the catches 6, butsnapping each time into the recess at the sides thereof, so thatbackward turning is impossible unless the part 5 be held outward beyondthe outer ends of the catches 6. For

accomplishing this to permit removal of the nut I provide therein a cam7, attached to the inner end of a pin 8, which is mounted in a hole inthe outer end of the nut and carries on its outer end a suitably-shapedhead 9, by which the cam can be turned. The cam is shaped so that whenturned to the position shown in Fig. 3 it will push the end of thespring or device 5 against the wall of the nut. Then the nut can beturned backward, because the said spring or device 5 no longer engageswith the shoulders 6. The said cam may be of thin metal, so that it willnot interfere with the free operation of the nut. The opposite end ofthe cam has a projecting arm 10, which prevents opposite rotation byengaging against the end of the member 5, as

shown in Fig. 4.

Other constructions and arrangements of the parts may log used, ifdesired, and I do not wish to rest'ric'tunyself to specific features ofconstruction.

I claim 1. In a nut-lock of the class described, a series of projectionson the axle, a nut having a closed end, a spring-plate inside the nutadjacent to the closed end to engage with said projections, a pinmounted in an opening in the closed end of the nut, and a cam on the endof the pin, within the nut, and operative to move the spring-plateagainst the walls of the nut.

2. In a nut-lock of the class described, a cries of projections on theaxle, a spring-plate mounted inside the nut and curving inward from thewalls thereof, a cam inside the nut and operative to push the plateagainst the walls of the nut, a projection on the cam to engage the endof the spring-plate when in locked position, a pin connected to the camand projecting outside the nut, and a head on the pin forming a hold.

3. In a nut-lock for vehicles, a series of projections on the end of theaxle, a spring-plate inside the nut and curving inward from the wallsthereof to engage with said projections,

a cam inside the nut and operative to push the In testimony whereof Ihereto affix my sigplate against the Walls of the nut out of enl naturein the presence of two Witnesses. gagement With the projections on theaxle, GEORGE 7 PETER [L Q] means for holding the cam against backward Qrotation when the nut is locked, and means for Witnesses:

turning the cam to release the plate from the FRED. W. DUENOKEL,projections, substantially as specified. J. D. RIPPEY.
